The martial status distribution of the U.S. Male Population, age 15 and older is as shown below. (Picture) Suppose that a random sample of 400 U.S young adult males, 18-24 years old, yielded the following frequency distribution. We are interested in whether this age group of males fits the distribution of the U.S. adult population at the 5% level. Calculate the frequency one would expect when surveying 400 people. Fill in the table below, rounding to two decimal places. (Chart in picture below) 1. What are degrees of freedom? (Enter an exact number as an integer, fraction, or decimal.) 2. What is test statistic? (Round your answer to two decimal places.) 3. Alpha (Enter an exact number as an integer, fraction, or decimal.) a= ?
